Selective hydrogen adding equipment for living organism applicable
fluid
Abstract
A selective hydrogen adding equipment for supplying hydrogen to
a living organism applicable fluid includes a hydrogen generating
system, that contains a hydrogen generating agent as an essential
component, a hydrogen bubble forming implement, that stores the
hydrogen generating system and has a gas/liquid separating section
including a gas-permeable film or an open-close valve, and a closed
container to accommodate the hydrogen adding equipment. The
gas/liquid separating section vents hydrogen gas generated by a
contact reaction between the hydrogen generating agent and water or
water vapor, the gas/liquid separating section avoids the water
from flowing out and/or avoids the living organism applicable fluid
from flowing in. The gas/liquid separating section allows water
vapor of the living organism applicable fluid to flow in the
hydrogen bubble forming implement so as to contact with the
hydrogen generating agent.

Description
BACKGROUND OF THE INVENTION
1. Technical Field of the Invention
The present invention relates to a selective hydrogen adding
equipment for living organism applicable fluid.
2. Description of the Related Art
As a method of producing living organism applicable
hydrogen-contained fluid, known in the art are a method using a
hydrogen water electrolytically generating apparatus for household
use and a method causing metal pieces of metal magnesium as a
hydrogen generating agent to contact with living organism
applicable fluid (Japanese Patent Application Publication No.
2007-167696).

SUMMARY OF THE INVENTION
Problems to be Solved by the Invention
In the case of obtaining living organism applicable
hydrogen-contained fluid using hydrogen generating agent, the
hydrogen generating agent may possibly change properties of the
living organism applicable fluid when dissolving hydrogen molecules
into the living organism applicable fluid. For example, if the
hydrogen generating agent is metal magnesium, then magnesium ions
are dissolved into the living organism applicable fluid to shift
the pH thereof toward alkaline side in accordance with the
following Formulae (1) and (2) when generating hydrogen.
Mg+2H.sub.2O.fwdarw.Mg(OH).sub.2+H.sub.2 Formula (1)
Mg(OH).sub.2.fwdarw.Mg.sup.2++2OH.sup.- Formula (2)
However, it is not desirable in general to change, before and after
the hydrogen generating reaction, constituents of the living
organism applicable fluid having been already made up naturally or
artificially. The change in constituents may in turn lead to
altering the flavor of living organism applicable fluid, such as
tea and mineral water.
Therefore, equipment for producing living organism applicable
hydrogen-contained fluid is desired which does not change
constituents of living organism applicable fluid.
Besides, only "food additives" are officially permitted as
additives allowed for contacting with articles of food under the
Food Sanitation Act.
Accordingly, when producing living organism applicable
hydrogen-contained fluid using hydrogen generating agent, it
violates the Food Sanitation Act to cause magnesium or hydrogenated
product as the hydrogen generating agent to directly contact with
living organism fluid.
Means for Solving the Problems
Through preparing a hydrogen generating system which contains a
hydrogen generating agent such as metal aluminum or metal magnesium
as an essential constituent, storing the hydrogen generating system
in a hydrogen bubble forming implement having a gas/liquid
separating section which is devised so as to release hydrogen gas
while substantially not making water flow in, and/or to release
hydrogen gas while substantially not making water flow out, and
causing the hydrogen generating agent and generating-purpose water
to react in the hydrogen bubble forming implement, the hydrogen gas
generated from the hydrogen bubble forming implement is dissolved
into living organism applicable fluid substantially without causing
the generating-purpose water having been used for the hydrogen
generating reaction to flow out into the living organism applicable
fluid, thereby to solve the problems. Further, the hydrogen gas is
supplied to a closed container gas phase section storing the living
organism applicable fluid thereby to solve the problems.
Furthermore, high pressure and high concentration hydrogen gas in
the gas phase is dissolved into the living organism applicable
fluid through shaking of the closed container, thereby providing
high concentration or supersaturated living organism applicable
hydrogen-contained fluid to solve the problems.
Advantageous Effect of the Invention
By supplying hydrogen into the living organism applicable fluid
using such means, the living organism applicable hydrogen-contained
fluid can be obtained without changing properties of the living
organism applicable fluid. Moreover, using such means also allows
high concentration hydrogen beverages to be easily produced without
altering any flavor of beverages regardless of locations, such as
home, workplace, street, and storefront.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Hereinafter, embodiments of the present invention will be
described.
Living organism applicable fluid in the present invention is a
fluid to be applied to living organisms, such as water or water
solution, which is an objective to be dissolved therein with
hydrogen using the present invention. Examples of living organism
applicable fluid include water as well as soft-drinks and beverages
such as tea and coffee. Living organism applicable
hydrogen-contained fluid to be obtained by dissolving hydrogen into
the living organism applicable fluid is applied to living organisms
via inhalation (atomization), drinking, injection, and the like,
but is not limited thereto. While an active constituent of the
living organism applicable hydrogen-contained fluid and
high-concentration or supersaturated living organism applicable
hydrogen-contained fluid is hydrogen and the functionality thereof
is primarily inhibition of oxidative stress, the functionality is
not limited thereto.
Hydrogen generating agent in the present invention is a substance
which generates hydrogen. Examples of hydrogen generating agent
include substances generating hydrogen by contacting with water,
such as metals having higher ionization tendency than hydrogen and
hydrogenated compounds including metal hydride. In consideration of
the Food Sanitation Act and the safety of the resulting reaction
products, it is preferred to use metals having higher ionization
tendency than hydrogen (magnesium, aluminum, zinc, iron, cobalt,
etc), which are food additives. Among them, metal aluminum is
preferably used from the viewpoints of aesthetic aspect, cost, and
safety in handling.
Generating-purpose water or water vapor in the present invention is
a liquid or vapor for causing hydrogen gas to be generated in a
hydrogen bubble forming implement through contacting with the
hydrogen generating agent. Examples of such generating-purpose
water or water vapor include tap water, clarified water,
ion-exchanged water, purified water, pure water, RO water, their
water vapor and the like, but are not limited thereto. The
above-described living organism applicable fluid in itself or its
vapor may also be used as the generating-purpose water or water
vapor. Regardless of contained components, hardness, and liquid
properties, any liquid or vapor including water or water vapor may
be used as the generating-purpose water or water vapor in the
present invention.
The hydrogen bubble forming implement of the present invention is
characterized by isolating the hydrogen generating system from the
living organism applicable fluid and delivering hydrogen gas, which
has been generated in the hydrogen bubble forming implement, to the
living organic applicable fluid via a gas/liquid separating section
of the hydrogen bubble forming implement. The equipment of the
present invention including the hydrogen bubble forming implement
can be accommodated in a closed container so as to be a separate
apparatus from the closed container for accommodating it or to be a
structural site incorporated in the closed container.
Such a gas/liquid separating section is characterized, for example,
by being devised such that a valve (such as a check valve or a ball
valve), a gas permeable film (such as anion-exchange membrane or
cation-exchange membrane) or the like is included as a component or
material thereby to vent hydrogen gas generated by the contact
reaction between the hydrogen generating system and the
generating-purpose water and to substantially avoid the
generating-purpose water from flowing out and/or avoid the living
organism applicable fluid from flowing in. The water vapor of the
living organism applicable fluid, however, can flow in the hydrogen
bubble forming implement through the gas/liquid separating section.
The water vapor causes hydrogen gas to be generated in a hydrogen
bubble forming implement through contacting with the hydrogen
generating agent.
Such devising includes providing an equipment for producing living
organism applicable hydrogen-contained fluid, which has a hydrogen
bubble forming implement provided with a gas/liquid separating
section having a gas-permeable film which is poorly-permeable or
non-permeable for water and permeable for hydrogen gas and of which
material (fabric, paper, plastic, rubber, ceramic, etc) and
thickness are not limited, wherein the equipment for producing
living organism applicable hydrogen-contained fluid is
characterized in that the hydrogen generating system or its
hydrogen generating agent is processed for thermal insulation and,
if necessary, the hydrogen bubble forming implement is processed
for heat retention. Further, the equipment according to the present
invention may also be devised to have an opening and closing
section capable of opening and closing the gas/liquid separating
section or a part of the hydrogen bubble forming implement, thereby
allowing the hydrogen generating system and the generating-purpose
water to be put into the hydrogen bubble forming implement via the
opening and closing section.
Here, the thermal insulation process for the hydrogen generating
system or the hydrogen generating agent therein is aimed at
suppressing the increased reaction heat caused by the grain form of
the hydrogen generating agent, which is employed for the reason of
facilitating the hydrogen generating reaction. Examples of such
process include, such as, but not limited to, covering by a cover
material the hydrogen generating system or the hydrogen generating
agent therein, tableting or solidifying the hydrogen generating
system or the hydrogen generating agent therein, and forming a
fireproof layer through the generation of by-products due to the
hydrogen generating reaction.
In addition, the thermal insulation process in the present
invention also includes using as the hydrogen generating agent a
metal raw material of which the exothermic reaction is moderate or
less.
Here, the cover material is operative: to maintain portions of the
hydrogen generating system in a status where the portions are
adjacent to each other thereby to enhance the efficiency of the
hydrogen generating reaction; to prevent the reaction heat during
the hydrogen generating reaction from directly transferring to the
gas-permeable film of the gas/liquid separating section thereby to
avoid the deterioration and degradation of the gas-permeable film;
and, in the case that the hydrogen generating system has pH
adjuster, to avoid the degradation of the gas-permeable film caused
from the acidity or alkalinity thereof. In addition, the cover
material also has a feature that it is permeated with hydrogen gas
and water but is not permeated with the hydrogen generating agent
and reaction residues thereof. Therefore, it is desirable that the
pore size of the cover material is 1,000 .mu.m or less, preferably
500 .mu.m or less, more preferably 150 .mu.m or less, and most
preferably 50 .mu.m or less.
Here, tableting or solidifying is aimed at employing compression
forming (tablet forming) possibly in combination with appropriate
diluents thereby to optimize the balance between the efficiency of
the hydrogen generating reaction caused by the hydrogen generating
system or the hydrogen generating agent therein and the suppression
of the reaction heat. Even if a metal is used as the hydrogen
generating agent, the above-described method may tablet or solidify
metal grains or powder of that metal thereby to suppress the
reaction heat during the hydrogen generating reaction while
ensuring enough surface area for contributing to the reaction. For
example, if such tableting or solidifying is performed by tablet
forming, in order to ensure certain spaces among grains and to
increase the surface area while avoiding shape losing, it is
desirable that the tableting pressure is, such as, but not limited
to, within the range from 0.1 kN to 100 kN, preferably 0.3 kN to 50
kN, more preferably 0.5 kN to 20 kN, and furthermore preferably 0.5
kN to 10 kN. In addition, such tablets or solidified materials may
also be held in one or more further cover materials.
Here, forming a fireproof layer through the generation of
by-products due to the hydrogen generating reaction is intended to
include, such as, but not limited to, avoiding the probability of
heat generation due to metal aluminum possibly even remaining after
the hydrogen generating reaction, using the fire-resistance of
alumina cement as the reduction product in the hydrogen generating
reaction where the hydrogen generating system includes metal
aluminum as the hydrogen generating agent and calcium oxide or
calcium hydroxide as the pH adjuster.
Here, using a metal raw material of which the exothermic reaction
is moderate or less is using a metal raw material characterized in
that the temperature thereof is below 50 degrees C. when measured
by a "metal raw material heat generation temperature measurement
method" as will be described hereinafter or the metal raw material
requires 5 seconds or more before reaching 50 degrees C. if
exceeding 50 degrees C.
The "metal raw material heat generation temperature measurement
method" is a method for measuring the temperature of an arbitrary
metal raw material when causing a hydrogen generating system, which
is comprised of the metal raw material 500 mg and malic acid
(DL-malic acid: FUSO CHEMICAL CO., LTD., for example) 500 mg, to
react with tap water (Fujisawa city tap water, for example) 500 mg
of water temperature 25 to 26 degrees C. as the generating-purpose
water in a polypropylene test tube of about 16.0 mL volume and
about 17.times.100 mm (Test Tube with 2-position Cap, 17.times.100
mm, 16.0 mL volume, Total Length: 100 mm, Outer Diameter: 16.5 mm,
Inner Diameter: 15 mm, Cap Size: 20.0.times.17.5 mm, catalog No.
222-2393-080 available from BM Equipment Co., Ltd., for example).
Note that, if the metal raw material is aluminum as being
amphoteric metal, then aluminum potassium sulfate (aluminum
potassium sulfate: Wako Pure Chemical Industries, Ltd., for
example) may be used as alkaline agent.
Specifically, the measurement of temperature of metal raw material
includes disposing the above hydrogen generating system in a
polypropylene test tube of about 16.0 mL volume and about
17.times.100 mm, then closing it with a cap, and injecting the
generating-purpose water using a dropper from a cap opening (an
opening of 5 mm diameter herein) previously provided at the center
area of the cap. Immediately thereafter, a previously warmed-up
digital thermometer (TANITA TT-508: TANITA Corporation) is inserted
deeply into the inside of the test tube to contact the thermometer
heat sensor unit (4 mm diameter herein) with the metal raw material
thereby performing the measurement. Note that, if the diameter of
the cap opening and the diameter of the thermometer heat sensor
unit is the same, then the cap may possibly fly away due to
hydrogen gas generated in the tube, so a space of about 1 mm may
have to be provided between the cap opening and the thermometer
heat sensor unit.
If using a metal raw material of which the exothermic reaction is
moderate or less, i.e. the temperature thereof is below 50 degrees
C. when measured by such a "metal raw material heat generation
temperature measurement method" or the metal raw material requires
5 seconds or more before reaching 50 degrees C. in the case of
exceeding 50 degrees C., then the extent is relatively small where
the high-temperature metal raw material may fly away with the
generating-purpose water during the exothermic reaction (hydrogen
generating reaction). If, however, using a metal raw material of
which the exothermic reaction is severe, i.e. the temperature
thereof reaches 50 degrees C. within 5 seconds, then the
high-temperature metal raw material may fly away with the
generating-purpose water during the exothermic reaction (hydrogen
generating reaction) and probably adhere to the gas/liquid
separating section or the inner wall of the hydrogen bubble forming
implement, so it is not preferred for the thermal insulation
process in the present invention.
Moreover, if the exothermic reaction is gentle such that reaching
50 degrees C. requires 5 seconds or more, then there is an
additional merit in handling the equipment that users of the
present invention can release the equipment into the living
organism applicable fluid container before they physically sense
the significant heat generation of the equipment itself associated
with the exothermic reaction.
Note that the metal raw material to be preferably used in the
present invention may not be unambiguously defined in terms of the
grain diameter or surface area of the metal raw material because
there are many cases that the metal raw material to be used in the
present invention is commercially produced as a powder-like product
including various grain diameter distribution or a tape-like
product appropriately processed to be stretched.
As metal elements for providing the metal raw material, among
lithium, potassium, calcium, sodium, magnesium, aluminum,
manganese, zinc, chrome, iron, cadmium, cobalt, nickel, tin, and
lead which are metals having higher ionization tendency than
hydrogen, metals not having unduly high ionization tendency and
having good handling ability, such as magnesium, aluminum,
manganese, zinc, iron, cobalt, and nickel, are preferably used.
Among them, magnesium, aluminum, zinc, iron, and cobalt are
particularly preferable because the safety thereof for living
organism is high. Note, however, that the same metal element may be
such that "the exothermic reaction is moderate or less" or may be
alternatively such that "the exothermic reaction is severe"
depending on the form of the metal raw material, and therefore, the
metal raw material to be preferably used in the present invention
may not be unambiguously defined in terms only of the metal
element.
Therefore, when the thermal insulation process in the present
invention employs a method "using a metal raw material of which the
exothermic reaction is moderate or less", it is preferred that an
available metal raw material is appropriately determined by the
above "metal raw material heat generation temperature measurement
method".
It should be noted that the merit is obtained where an available
metal raw material may be selected by the "metal raw material heat
generation temperature measurement method" so as not to necessarily
require the previously described other thermal insulation
processes, such as "covering by a cover material", "tableting or
solidifying", and "forming a fireproof layer through the generation
of by-products due to the hydrogen generating reaction".
It should also be noted that various types of such thermal
insulation processes are effective even in the case where a valve
is used for the gas/liquid separating section.
Besides, the heat retention process for the hydrogen bubble forming
implement herein is aimed at smoothly progressing the hydrogen
generating reaction in the hydrogen bubble forming implement
through buffering the direct contact between the hydrogen bubble
forming implement and the living organism applicable fluid existing
outside thereof to suppress the hydrogen bubble forming implement
from being cooled by the living organism applicable fluid.
Examples of such heat retention process include, such as, but not
limited to, imparting an appropriate thickness to the outer wall of
the hydrogen bubble forming implement or covering with an outer
shell the periphery of the hydrogen bubble forming implement and,
if necessary, providing an appropriate air layer between the
hydrogen bubble forming implement and the outer shell thereby to
prevent the heat from escaping directly from water.
Although not limited to, it is desirable that the thickness of the
hydrogen bubble forming implement is 0.1 mm or more, preferably 0.5
mm or more, and further preferably 1.0 mm or more. The air layer
provided between the hydrogen bubble forming implement and the
outer shell is such that, but not limited to, the distance
therebetween is desirable to be 0.1 mm or more, preferably 0.5 mm
or more, and further preferably 1.0 mm or more.
For example, in a hydrogen generating system containing aluminum as
the hydrogen generating agent and alkaline agent, such as calcium
oxide or calcium hydroxide, which is a food additive, as the pH
adjuster as will be described later, the reaction rate of the
hydrogen generating reaction significantly varies depending on the
water temperature of the living organism applicable fluid
contacting the hydrogen bubble forming implement in which the
hydrogen generating system is stored. More specifically, when the
water temperature of the living organism applicable fluid is 4
degrees C., the hydrogen generating reaction considerably slows
down compared to the case where the water temperature is 20 degrees
C., whereas on the other hand, even if the water temperature of the
living organism applicable fluid is 4 degrees C., on the occasion
that the heat retention of the hydrogen bubble forming implement is
appropriately promoted such as by covering with an outer shell the
periphery of the hydrogen bubble forming implement and providing an
appropriate air layer, the hydrogen generating reaction comes to be
faster than the case of no heat retention.
Therefore, in the present invention, it is preferred in general
that the hydrogen bubble forming implement is subjected to heat
retention process in order to reduce the time duration until when
the living organism applicable fluid will contain sufficient amount
of hydrogen molecules.
It should be noted that such heat retention processes are effective
even in the case where a valve is used for the gas/liquid
separating section.
Similarly, it is further desirable that the hydrogen generating
system contains exothermic agent for facilitating the hydrogen
generating reaction.
For example, in a hydrogen generating system containing aluminum as
the hydrogen generating agent and calcium oxide as the pH adjuster,
a heat of hydration while calcium oxide is hydrated with the
generating-purpose water to generate calcium hydroxide may be
utilized for the hydrogen generating reaction caused by aluminum
and calcium hydroxide. In this case, calcium oxide acts not only as
the pH adjuster but as the exothermic agent. Therefore, even in the
case where the hydrogen generating system contains aluminum as the
hydrogen generating agent and calcium hydroxide as the pH adjuster,
it is preferred to further contain calcium oxide as the exothermic
agent.
In addition, another embodiment of the present invention involves,
for example, providing a valve in the gas/liquid separating section
to prevent the living organism applicable fluid from flowing into
the hydrogen bubble forming implement. This allows for preventing
water having flowed into the hydrogen bubble forming implement from
flowing out again to the living organism applicable fluid during
the shaking and the like, while the hydrogen gas generated in the
hydrogen bubble forming implement is capable of being released into
the living organism applicable fluid. More specifically, such a
valve provided in the gas/liquid separating section is an
open-close type valve which separates the internal and external of
the hydrogen bubble forming implement, and which is to be opened by
a gas pressure of the hydrogen gas generated in the internal of the
hydrogen bubble forming implement owing to the reaction between the
hydrogen generating system and the generating-purpose water thereby
to exhaust the hydrogen gas into the external of the hydrogen
bubble forming implement, while to be naturally or artificially
closed after the exhaust through the gravity force or the water
pressure from the external of the hydrogen bubble forming
implement. The valve is characterized by substantially not causing
the organism-applicable fluid existing at the external of the
hydrogen bubble forming implement to flow into the internal thereof
except for during the exhaust of the hydrogen gas.
FIG. 1 illustrates an example of the gas/liquid separating section
employing such an open-close type valve. In this case, the
gas/liquid separating section is comprised of an open-close type
valve (a) and a recessed component (b) made of plastic with which
the valve is combined. The open-close type valve is configured such
that one axial part (a-2) extends from a lampshade-like head part
(a-1) while an annular flange (a-3) is shaped at a midway along the
axial part so as to surround it. In addition, the recessed
component is configured such that the base plate thereof is formed
therein with a center hole (b-1) and three holes (b-2) each spread
out in a fan-like form are opened to surround the center hole
(b-1), while an edge (b-3) remains as a peripheral portion of the
base plate to be engaged with the head part of the valve. This base
plate has an area with such an extent that the head part (a-1) of
the valve is just stored, and when the head part (a-1) of the valve
has been stored, the axial part (a-2) of the valve is allowed to
pass through the above-described center hole (b-1) opened at the
center portion, whereas the annular flange (a-3) surrounding the
axial part is not allowed to easily pass therethrough due to its
size. However, if the axial part (a-2) having passed through the
center hole (b-1) opened at the center portion of the base plate of
the recessed component is pulled down from below, then the annular
flange (a-3) surrounding the axial part of the valve passes through
the hole (b-1) of the base plate while being deformed, thereby to
allow for combining the valve (a) and the recessed component
(b).
As the gas pressure of hydrogen gas generated in the hydrogen
bubble forming implement increases, the hydrogen gas is exhausted
while the head part of the open-close type valve having been
located at the base plate of the recessed component is pressed and
opened, but the annular flange surrounding the axial part is
engaged with the center hole opened at the center portion of the
base plate of the recessed component, and the open-close valve is
thus prevented from dropping off from the recessed component even
due to the hydrogen gas pressure during the exhaust.
In addition to this, by further decreasing the amount of the
generating-purpose water to be introduced into the hydrogen bubble
forming implement, the generating-purpose water is prevented from
flowing out into the living organism applicable fluid even during
the exhaust of hydrogen gas from the valve.
With respect to a target of the usage of the generating-purpose
water, when the hydrogen generating system is removed (in the case
where the hydrogen generating system is covered by a cover
material, removed with the cover material) after the
generating-purpose water has been introduced into the hydrogen
bubble forming implement storing the hydrogen generating system, it
is desirable that the amount of the generating-purpose water
remaining in the hydrogen bubble forming implement is 10 cc or
less, preferably 5 cc or less, more preferably 3 cc or less, and
most preferably 1 cc or less.
Moreover, for the sake of avoiding the flowing out of such excess
generating-purpose water, it is desirable that substances or
materials having water absorbability, such as absorbent beads,
ion-exchange resin (dry ion-exchange resin is further preferable
because of higher water absorbability as will be described later),
absorbent paper, hyaluronic acid, and polyacrylic acid, are
involved in the hydrogen bubble forming implement or in the cover
material as will be described later, etc.
Note that a part or whole of the hydrogen bubble forming implement
may be configured of such a gas/liquid separating section. It is
desirable that materials provided with the hydrogen bubble forming
implement for parts other than the gas/liquid separating section
are those, such as acrylic resin and other synthetic resins, which
are scarcely permeated with water and hard to be corroded by
water.
Another embodiment of the present invention involves, for example,
providing the gas/liquid separating section with a gas-permeable
film which allows water to flow into the hydrogen bubble forming
implement while preventing water to flow out from the hydrogen
bubble forming implement, i.e. controls inflow and outflow of water
irreversibly. By contacting the equipment for producing living
organism applicable hydrogen-contained fluid having such a
gas/liquid separating section with the living organism applicable
fluid, a part of the living organism applicable fluid flows into
the hydrogen bubble forming implement via the gas/liquid separating
section. The living organism applicable fluid having flowed thereto
reacts as the generating-purpose water with the hydrogen generating
system in the hydrogen bubble forming implement thereby to generate
hydrogen gas. This causes the generated hydrogen gas to be released
into the living organism applicable fluid while avoiding the
generating-purpose water to flow out into the living organism
applicable fluid owing to the block by the gas-permeable film.
The hydrogen generating system in the present invention may contain
agents, such as sequestering agent and pH adjuster, which
facilitate the hydrogen generating reaction, in addition to the
hydrogen generating agent.
Such a sequestering agent contains one or more substances for
generating one or more substances which are absolutely undissolved
or scarcely dissolved in water and has a property for adsorbing
metal ions in the hydrogen bubble forming implement or in the cover
material. Insoluble or poorly-soluble metal sequestering agents
such as cation exchange resin are preferably used. Among them,
hydrogen ion type cation exchange resins are more preferred because
of having an additional function as pH adjuster, wherein the
hydrogen ion type cation exchange resins include an acidic cation
exchange resin having sulfonic acid group as exchange group and an
acidic cation exchange resin having carboxylic acid group as
exchange group, both of which adsorb metal ions and release
hydrogen ions (H.sup.+).
Examples of the pH adjuster in the present invention include
substances having properties for inhibiting (neutralizing or
preventing the generation of) hydroxide ions (OH.sup.-) by
supplying hydrogen ions (H.sup.+), such as citric acid, adipic
acid, malic acid, acetic acid, succinic acid, gluconic acid, lactic
acid, phosphoric acid, hydrochloric acid, sulfuric acid, and other
acids, and further include substances for removing hydroxide ions
by being subjected to hydrolysis to form insoluble hydroxide. In
addition to acid, alkaline agent such as calcium hydroxide, calcium
oxide or anion-exchange resin may also be used when amphoteric
metal such as aluminum or zinc is used as the hydrogen generating
agent. Among them, it is preferred to use alkaline agent, such as
calcium hydroxide (hydrated lime), calcined lime (calcium oxide),
burnt calcium, magnesium oxide, magnesium hydroxide, or
anion-exchange resin, which is a food additive. A hydrogen
generating reaction accelerator that reacts with metal, such as
aluminum, which has higher ionization tendency than hydrogen and
which is a food additive, to generate poorly-soluble products is
suitable for objects of the present invention of substantially not
changing properties of the living organism applicable fluid,
because the hydrogen generating reaction accelerator suppresses
metal ions of the metal from re-dissolving after the hydrogen
generating reaction.
In addition, it is preferred that, in order to suppress time
degradation of the hydrogen generating agent, the hydration number
and the water content ratio of the pH adjuster, such as an
appropriate acid or alkaline agent, contained in the hydrogen
generating system are lower. More specifically, with respect to the
hydration number, it is desirable to be trihydrate or lower,
preferably dihydrate or lower, more preferably monohydrate or
lower, and most preferably nonhydrate or anhydride. It is also
desirable that the water content ratio is 40 weight % or less,
preferably 30 weight % or less, more preferably 20 weight % or
less, and most preferably 15 weight % or less.
Concepts of the living organism applicable high concentration
hydrogen-contained fluid in the present invention include a living
organism applicable hydrogen-contained fluid of which the dissolved
hydrogen concentration in the fluid is 0.01 ppm or more, preferably
0.1 ppm or more, and more preferably 1.0 ppm or more. Concepts of
the living organism applicable supersaturated hydrogen-contained
fluid in the present invention involve a situation where the
dissolved hydrogen concentration is higher than or equal to the
degree of solubility at ordinary temperatures and pressures, and
include a living organism applicable high concentration
hydrogen-contained fluid of 1.6 ppm or more, 2.0 ppm or more, 3.0
ppm or more, 4.0 ppm or more, 5.0 ppm or more, 6.0 ppm or more, 7.0
ppm or more, 8.0 ppm or more, 9.0 ppm or more, and 10.0 ppm or
more.
Note that the selective hydrogen adding equipment for living
organism applicable fluid according to the present invention, which
is configured by accommodating the hydrogen generating system into
the hydrogen bubble forming implement, may be disposed within a
container for storing the living organism applicable fluid so as to
be, such as, in the living organism applicable fluid, in the air
space of the container, or in the outer space of the container.
Note also that the container is preferred to be a closed
container.
When using a closed container as the container, the hydrogen gas
generated in the hydrogen bubble forming implement by the reaction
between the hydrogen generating system and the generating-purpose
water is released via the gas/liquid separating section of the
hydrogen bubble forming implement into the closed container storing
the living organism applicable fluid and forms a hydrogen gas phase
of high pressure and high concentration. Note that the applicant(s)
have found out that, even when the selective hydrogen adding
equipment for living organism applicable fluid according to the
present invention is disposed in the living organism applicable
fluid, most of the generated hydrogen molecules first transfer
toward the air space of the closed container without dissolving
into the living organism applicable fluid.
Further to say, the applicant(s) have found out that, when the
hydrogen generating agent is disposed in the living organism
applicable fluid after being stored in the hydrogen bubble forming
implement, the amount of hydrogen dissolving into the living
organism applicable fluid immediately after being put into the
fluid is further less than the case where the hydrogen generating
agent is put in a bared state into the living organism applicable
fluid without being stored in the hydrogen bubble forming
implement.
That is, hydrogen molecules generated from the hydrogen generating
agent not stored in the hydrogen bubble forming implement come to
form clusters or microscopic bubbles while directly dissolving into
the living organism applicable fluid, whereas, when hydrogen
molecules are released into the living organism applicable fluid
via the gas/liquid separating section of the hydrogen bubble
forming implement, the hydrogen bubble forming implement acts as a
kind of stopper for the hydrogen gas, thereby resulting in that the
hydrogen molecules once gather together with an appropriate amount
at the vicinity of the inner wall of the gas/liquid separating
section and are thereafter released as hydrogen gas bubbles from
the gas/liquid separating section. In other words, when released
into the living organism applicable fluid, the hydrogen molecules
are released as hydrogen gas bubbles already having certain
dimensions.
This is visually observed. For example, if the selective hydrogen
adding equipment for living organism applicable fluid according to
the present invention is disposed in the closed container storing
the living organism applicable fluid and the container is left for
a while in a laid form, then the hydrogen gas generated in the
hydrogen bubble forming implement releases intermittently hydrogen
bubbles from the gas/liquid separating section while causing the
volume of the hydrogen gas phase to be progressively increased. In
other words, the released hydrogen gas is of large bubble size,
therefore moving upward in water to rapidly transfer into the gas
phase in the closed container.
In general, among ones of ordinary skill in the art of producing
not only hydrogen-contained solution but other gas-contained
solution with expectation of some form of industrial use, it has
been considered that the important thing for producing a
high-concentration gas solution is to make the bubble size of the
gas be microscopic as much as possible thereby decreasing the
rising velocity of the bubbles toward the gas phase. At the time of
the present application, it still remains to be recognized as one
of primary technical issues in the art to make various industrial
gasses including hydrogen, oxygen or ozone be nano-bubbles.
Meanwhile, the inventors have found out that, in the case where
consumers attempt to obtain a living organism applicable high
concentration hydrogen-contained fluid at various locations, such
as home, workplace, street, and storefront, it is desirable to form
first the hydrogen gas phase in the closed container using hydrogen
gas of relatively large bubble size and increase the internal
pressure in the container, thereafter, if necessary, appropriately
shaking the closed container to collect the hydrogen gas from the
gas phase, than directly dissolving hydrogen molecules into the
living organism applicable fluid in the closed container which
stores the living organism applicable fluid including drinking
water and beverages, such as tea and coffee. Therefore, it is
desirable that the gas-permeable film or the valve to be used for
the gas/liquid separating section is such that, when the equipment
according to the present invention having the gas/liquid separating
section is disposed in clarified water, the average bubble diameter
of hydrogen gas bubbles generated during initial 10 minutes is 0.1
mm or more, preferably 0.3 mm or more, more preferably 0.5 mm or
more, and most preferably 1.0 mm or more, when measured by using
dynamic light scattering method or other appropriate method.
According to experiments performed by the inventors, in spite of
the fact that the dissolved hydrogen concentration in the living
organism applicable fluid increases up to approximately 0.7 ppm
after a lapse of 10 minutes from a situation where metal magnesium
as the hydrogen generating agent has been disposed in the living
organism applicable fluid in the closed container without being
stored in the hydrogen bubble forming implement, subsequent shaking
of the closed container merely increases the dissolved hydrogen
concentration up to approximately 0.9 ppm (approximately 1.3
times). In contrast, the dissolved hydrogen concentration in the
living organism applicable fluid slightly increases up to
approximately 0.2 ppm after a lapse of 10 minutes from a situation
where the same amount of metal magnesium as the hydrogen generating
agent has been disposed in the living organism applicable fluid in
the closed container with being stored in the hydrogen bubble
forming implement, whereas subsequent shaking of the closed
container drastically increases the dissolved hydrogen
concentration up to approximately 3.0 ppm (approximately 15
times).
Thus, it is desirable to accommodate in the closed container the
hydrogen adding equipment for living organism applicable fluid
according to the present invention, which is configured by storing
the hydrogen generating system in the hydrogen bubble forming
implement, and to appropriately shake the closed container, for the
purpose of increasing the dissolved hydrogen concentration in the
living organism applicable hydrogen-contained fluid.
In this case, the closed container in the present invention is
intended to include a container which is devised not to expose the
contents in the container to the air. Examples of the closed
container include containers with lids, such as PET bottles and
aluminum bottles with caps. It is desirable that the container has
a portable form and volume in order for a person to easily shake it
in his/her hand. It is also desirable that the container is of 2 L
or less, preferably 1 L or less, and most preferably 0.5 L or less,
but not limited thereto.
Preferred materials for the closed container are to have low
hydrogen permeability. As the hydrogen permeability is lower, the
generated hydrogen is hard to escape from the container system.
The hydrogen permeability of the closed container in the present
invention is measured as follows. That is, with reference to the
method described in Patent Application No. 2009-221567 or the like,
hydrogen dissolved water is prepared to stably keep approximately
the saturated concentration (1.6 ppm at 20 degrees C. and 1 atm)
with the volume of 20 times of the inner volume of a closed
container as an object to be measured, and the closed container is
then immersed during 5 hours in the hydrogen dissolved water after
being fully filled with clarified water (charcoal-treated water,
such as Fujisawa city tap water treated to pass through a charcoal
column).
Thereafter, the dissolved hydrogen concentration in the clarified
water is measured, wherein the container of lower hydrogen
permeability in the present invention involves a closed container
with dissolved hydrogen concentration of 1,000 ppb or lower,
preferably 500 ppb or lower, more preferably 100 ppb or lower, and
most preferably 10 ppb or lower.
It is desirable that the closed container has a pressure-proof
property capable of resisting the increasing of the inner pressure
due to the generation of hydrogen. Specifically, it is desirable to
be a pressure-proof container capable of resisting the inner
pressure of 0.11 MPa as absolute pressure, preferably 0.4 MPa, more
preferably 0.5 MPa, and most preferably 0.8 MPa. A PET bottle for
carbonated drink or any appropriate bottle may be preferably used.
It is also desirable that the closed container comprises at the
mouth thereof a mechanism for releasing the pressure (vent slot)
midway through opening the cap for the purpose of safety
opening.
The shaking in the present invention is to give a physical impact
or shock to the closed container thereby replacing the dissolved
gas such as dissolved oxygen in the living organism applicable
fluid with hydrogen gas while contacting the living organism
applicable fluid and the gas-phase hydrogen with each other in the
closed container. The shaking in the present invention involves
natural shaking using hand or hands as well as artificial shaking
using a machine. Examples of such artificial shaking include
shaking by using a shaking machine, an agitator, an ultrasonic
generator, and other appropriate apparatuses.
Moreover, in order for hydrogen gas to be further accumulated in
the gas phase in the closed container, it is desirable to start the
shaking after 1 minute has elapsed, preferably 2 minutes, more
preferably 4 minutes, furthermore preferably 8 minutes, and most
preferably 10 minutes, from the time when the selective hydrogen
adding equipment for living organism applicable fluid according to
the present invention was disposed in the closed container.
Note that an exemplary case of typical and natural shaking in the
present invention is as follows. That is, the shaking is performed
by a Japanese man of 30's having an average physical size, who
holds the middle portion of the closed container by his dominant
hand and moves only the wrist to shake it such that the cap forms
into an arch above the wrist with a pace of 2 strokes per second,
total 120 strokes.
Further, in order to facilitate the dissolution of the
high-pressure and high-concentration hydrogen gas into the living
organism applicable fluid, it is desirable that the time period for
the shaking is 5 seconds or longer for the natural shaking,
preferably 10 seconds or longer, more preferably 15 seconds or
longer, and still preferably 30 seconds or longer.
Moreover, it is preferred that the shaking is such that, when
performing the shaking after disposing the selective hydrogen
adding equipment for living organism applicable fluid according to
the present invention in the living organism applicable fluid, the
dissolved hydrogen concentration in the living organism applicable
fluid is enhanced twice or higher of the dissolved hydrogen
concentration before the shaking, preferably 3 times or higher,
more preferably 4 times or higher, 5 times or higher, 6 times or
higher, 7 times or higher, 8 times or higher and 9 times or higher
in this order, and further preferably 10 times or higher.
Furthermore, it is preferred that the inner pressure in the closed
container before the shaking is higher than or equal to the
atmosphere pressure in order to obtain higher concentration living
organism applicable hydrogen-contained fluid, such as
supersaturated living organism applicable hydrogen-contained fluid
with 1.6 ppm or higher. The solubility of hydrogen molecules to the
living organism applicable fluid increases as the inner pressure
loaded by the generated hydrogen molecules to the closed container
increases, and exceeds the solubility at the normal temperature and
pressure in due time. The reason why the closed container storing
the hydrogen generating system is left for a while for example in
the examples as will be described later is to pressurize the closed
container from the inside by the generated hydrogen gas, and also
to allow for appropriately shaking the closed container under the
increased pressure thereby further facilitating the dissolution of
the hydrogen molecules to the living organism applicable
hydrogen-contained fluid.
Note that the conditions of not substantially changing the
constituents of the living organism applicable fluid in the present
invention include, such as, but not limited to, satisfying at least
either one of not changing the total hardness, not changing the
metal ion concentration related to the metal used as the hydrogen
generating agent, or not changing the pH.
Here, the conditions of not changing the total hardness of the
living organism applicable fluid include the following cases, but
are not limited thereto.
Such cases include a case where the total hardness (Ca hardness+Mg
hardness) in the living organism applicable hydrogen-contained
fluid of which the raw water is a certain living organism
applicable fluid is within an allowable range, such as, from (total
hardness of the raw water minus 25 ppm) to (total hardness of the
raw water plus 25 ppm), preferably from (total hardness of the raw
water minus 15 ppm) to (total hardness of the raw water plus 15
ppm), and more preferably from (total hardness of the raw water
minus 10 ppm) to (total hardness of the raw water plus 10 ppm).
Alternatively, such cases may include a case where a PET bottle for
carbonated drink (about 530 cc volume when filled with full water
to the mouth) is substantially filled with 515 cc of living
organism applicable fluid as being clarified water obtained by
dechlorination treating for tap water and having total hardness (Ca
hardness+Mg hardness) of approximately 55 to 65 ppm (clarified
water such as obtained by treating Fujisawa city tap water to pass
through a charcoal column), the nondestructive producing equipment
for high-concentration hydrogen solution according to the present
invention is disposed in the living organism applicable fluid, the
bottle is left to be laid flat during 10 minutes, and the total
hardness of the fluid after performing typical and natural shaking
(holding the middle portion of the PET bottle by one's dominant
hand and moving only the wrist such that the cap forms into an arch
above the wrist with a pace of 2 strokes per second, total 120
strokes) for the fluid is within an allowable range, such as, from
(total hardness of the raw water minus 25 ppm) to (total hardness
of the raw water plus 25 ppm), preferably from (total hardness of
the raw water minus 15 ppm) to (total hardness of the raw water
plus 15 ppm), and most preferably from (total hardness of the raw
water minus 10 ppm) to (total hardness of the raw water plus 10
ppm).
Here, the conditions of not changing the metal ion concentration
related to the metal used as the hydrogen generating agent include
the following cases, but are not limited thereto.
Such cases include a case where the metal ion concentration
(aluminum ion concentration when the equipment according to the
present invention uses aluminum as the hydrogen generating agent,
for example) in the living organism applicable hydrogen-contained
fluid of which the raw water is a certain living organism
applicable fluid is within an allowable range, such as, from (metal
ion concentration of the raw water minus 15 ppm) to (metal ion
concentration of the raw water plus 15 ppm), preferably from (metal
ion concentration of the raw water minus 10 ppm) to (metal ion
concentration of the raw water plus 10 ppm), more preferably from
(metal ion concentration of the raw water minus 5 ppm) to (metal
ion concentration of the raw water plus 5 ppm), furthermore
preferably from (metal ion concentration of the raw water minus 3
ppm) to (metal ion concentration of the raw water plus 3 ppm), and
most preferably from (metal ion concentration of the raw water
minus 1 ppm) to (metal ion concentration of the raw water plus 1
ppm).
Alternatively, such cases may include a case where a PET bottle for
carbonated drink (about 530 cc volume when filled with full water
to the mouth) is substantially filled with 515 cc of living
organism applicable fluid as being clarified water obtained by
dechlorination treating for tap water (clarified water such as
obtained by treating Fujisawa city tap water to pass through a
charcoal column), the producing equipment for living organism
applicable hydrogen-contained fluid according to the present
invention is disposed in the living organism applicable fluid, the
bottle is left to be laid flat during 10 minutes, and immediately
after performing typical and natural shaking (holding the middle
portion of the PET bottle by one's dominant hand and moving only
the wrist such that the cap forms into an arch above the wrist with
a pace of 2 strokes per second, total 120 strokes) for the fluid,
the metal ion concentration in the fluid related to the metal used
as the hydrogen generating agent in the producing equipment
(aluminum ion concentration when the equipment according to the
present invention uses aluminum as the hydrogen generating agent,
for example) is within an allowable range, such as, from (metal ion
concentration of the raw water minus 15 ppm) to (metal ion
concentration of the raw water plus 15 ppm), preferably from (metal
ion concentration of the raw water minus 10 ppm) to (metal ion
concentration of the raw water plus 10 ppm), more preferably from
(metal ion concentration of the raw water minus 5 ppm) to (metal
ion concentration of the raw water plus 5 ppm), furthermore
preferably from (metal ion concentration of the raw water minus 3
ppm) to (metal ion concentration of the raw water plus 3 ppm), and
most preferably from (metal ion concentration of the raw water
minus 1 ppm) to (metal ion concentration of the raw water plus 1
ppm).
Here, the conditions of not changing the pH include the following
cases, but are not limited thereto.
Such cases include a case where the pH in the living organism
applicable hydrogen-contained fluid of which the raw water is a
certain living organism applicable fluid is within an allowable
range, such as, from (pH of the raw water minus 3.0) to (pH of the
raw water plus 3.0), preferably from (pH of the raw water minus
2.0) to (pH of the raw water plus 2.0), more preferably from (pH of
the raw water minus 1.0) to (pH of the raw water plus 1.0), and
most preferably from (pH of the raw water minus 0.5) to (pH of the
raw water plus 0.5).
Alternatively, such cases may include a case where a PET bottle for
carbonated drink (about 530 cc volume when filled with full water
to the mouth) is substantially filled with 515 cc of living
organism applicable fluid as being clarified water obtained by
dechlorination treating for tap water and having pH of
approximately 7.0 to 7.8 (clarified water such as obtained by
treating Fujisawa city tap water to pass through a charcoal
column), the producing equipment for living organism applicable
hydrogen-contained fluid according to the present invention is
disposed in the living organism applicable fluid, the bottle is
left to be laid flat during 10 minutes, and immediately after
performing typical and natural shaking (holding the middle portion
of the PET bottle by one's dominant hand and moving only the wrist
such that the cap forms into an arch above the wrist with a pace of
2 strokes per second, total 120 strokes) for the fluid, the pH of
the fluid is within an allowable range, such as, from (pH of the
raw water minus 3.0) to (pH of the raw water plus 3.0), preferably
from (pH of the raw water minus 2.0) to (pH of the raw water plus
2.0), more preferably from (pH of the raw water minus 1.0) to (pH
of the raw water plus 1.0), and most preferably from (pH of the raw
water minus 0.5) to (pH of the raw water plus 0.5).
EXAMPLES
Hereinafter, examples of the present invention will be described.
Note that, when there is no particular explanation in the present
application, various gauges used for measuring various physicality
values are as follows: pH meter (including temperature indicator)
manufactured by Horiba, Ltd. (main body type: D-13, probe type:
9620-10D); and DH meter (dissolved hydrogen meter) manufactured by
DKK-Toa Corporation (main body type: DHDI-1, electrode (probe)
type: HE-5321, transponder type: DHM-F2).
Calcium hardness and magnesium hardness were measured by the
calmagite colorimetric method using water quality analyzer DR/4000
(manufactured by HACH Company).
Aluminum ion concentration was measured by the aluminon method
using the same water quality analyzer.
Example 1 (Illustrated as FIG. 2)
A hydrogen generating system (c-1) containing 300 mg of metal
magnesium (MG100: Kanto Metal Corporation) as the hydrogen
generating agent and further containing 1,500 mg of hydrogen ion
type cation exchange resin (obtained by thermally-drying "DIAION
Ion Exchange Resin SK1BH: Mitsubishi Chemical Corporation", a
commercially available strongly acidic ion exchange resin H-type
product) was enclosed and heat sealed in a cover material (Precise
Regular C5160: Asahi Kasei Corporation) (c-2), and then stored in
an acrylic resin tubular hydrogen bubble forming implement (c-3)
with that cover material. The selective hydrogen adding equipment
for living organism applicable fluid according to the present
invention was obtained by dropping generating-purpose water (c-4)
into the hydrogen bubble forming implement with such an extent of
wetting the cover material, and closing the opening of the hydrogen
bubble forming implement with the gas/liquid separating section
(FIG. 1).
Subsequently, a PET bottle for carbonated drink (about 530 cc
volume when filled with full water to the mouth) was substantially
filled with about 515 cc of clarified water (charcoal-treated water
obtained by treating Fujisawa city tap water to pass through a
charcoal column), and the selective hydrogen adding equipment for
living organism applicable fluid was then disposed into the
clarified water in the PET bottle.
Thereafter, the bottle was left to be laid flat during 10 minutes,
and one of the present inventors (Japanese man of 30's having an
average physical size) then held the middle portion of the PET
bottle by his dominant hand and moved only the wrist to shake it
such that the cap was forming into an arch above the wrist with a
pace of 2 strokes per second, total 120 strokes (total 60
seconds).
Measurements were done for pH, dissolved hydrogen concentration,
calcium (Ca) hardness, and magnesium (Mg) hardness of contained
fluid before and after shaking.
Example 2 (Illustrated as FIG. 3)
A hydrogen generating system (d-1) containing 300 mg of metal
magnesium (MG100: Kanto Metal Corporation) as the hydrogen
generating agent and further containing 1,500 mg of hydrogen ion
type cation exchange resin (obtained by thermally-drying "DIAION
Ion Exchange Resin SK1BH: Mitsubishi Chemical Corporation", a
commercially available strongly acidic ion exchange resin H-type
product) was enclosed and heat sealed in a cover material (Precise
Regular C5160: Asahi Kasei Corporation) (d-2), and then stored in
an acrylic resin tubular hydrogen bubble forming implement (d-3)
with that cover material. The selective hydrogen adding equipment
for living organism applicable fluid according to the present
invention was obtained by dropping water into the hydrogen bubble
forming implement with such an extent of wetting the cover
material, inserting the gas/liquid separating section described
with reference to FIG. 1 to be disposed into the tubular hydrogen
bubble forming implement so as just not to leave a space at the
middle portion, and opening one or more hydrogen gas permeable
holes (d-4) at a part of the outer wall of the hydrogen bubble
forming implement.
Subsequently, a PET bottle for carbonated drink (about 530 cc
volume when filled with full water to the mouth) was substantially
filled with about 515 cc of clarified water (charcoal-treated water
obtained by treating Fujisawa city tap water to pass through a
charcoal column), and the fringe of the hydrogen bubble forming
implement was then caused to engage with the PET bottle mouth
portion while the equipment was inserted into the mouth portion and
the cap was closed so as not to immerse the equipment in the water.
At that time, the hydrogen gas permeable holes were positioned
above the water level of the clarified water.
Thereafter, the bottle was left during 10 minutes, and one of the
present inventors (Japanese man of 30's having an average physical
size) then held the middle portion of the PET bottle by his
dominant hand and moved only the wrist to shake it such that the
cap was forming into an arch above the wrist with a pace of 2
strokes per second, total 120 strokes (total 60 seconds).
Measurements were done for pH, dissolved hydrogen concentration,
calcium (Ca) hardness, and magnesium (Mg) hardness of contained
fluid before and after shaking.

and further containing 900 mg of malic acid (DL-malic acid: FUSO
CHEMICAL CO., LTD.) was enclosed with water absorbent paper and
heat sealed in a cover material (Precise Regular C5160: Asahi Kasei
Corporation), and then stored in an acrylic resin tubular hydrogen
bubble forming implement with that cover material. The selective
hydrogen adding equipment for living organism applicable fluid
according to the present invention was obtained by dropping water
into the hydrogen bubble forming implement with such an extent of
wetting the cover material, inserting a stopper made of water
absorbent paper and in turn the gas/liquid separating section
described with reference to FIG. 1 to be disposed into the tubular
hydrogen bubble forming implement so as just not to leave a space
at the middle portion, and opening one or more hydrogen gas
permeable holes at a part of the outer wall of the hydrogen bubble
forming implement.
Subsequently, a PET bottle for carbonated drink (about 530 cc
volume when filled with full water to the mouth) was substantially
filled with about 515 cc of clarified water (charcoal-treated water
obtained by treating Fujisawa city tap water to pass through a
charcoal column), and the fringe of the hydrogen bubble forming
implement was then caused to engage with the PET bottle mouth
portion while the equipment was inserted into the mouth portion and
the cap was closed so as not to immerse the equipment in the water.
At that time, the hydrogen gas permeable holes were positioned
above the water level of the clarified water.
Thereafter, the bottle was left during 10 minutes, and one of the

As malic acid (500 mg), DL-malic acid (FUSO CHEMICAL CO., LTD.) was
used. As aluminum potassium sulfate (500 mg), aluminum potassium
sulfate (Wako Pure Chemical Industries, Ltd.) was used. As the
generating-purpose water (500 mg), Fujisawa city tap water with the
water temperature of 25 to 26 degrees C. was used. As the test
tube, Test Tube with 2-position Cap, 17.times.100 mm, 16.0 mL
volume (BM Equipment Co., Ltd.) was used. As the digital
thermometer, TANITA TT-508 (TANITA Corporation) was used.
Dissolved hydrogen (DH) concentration achieved by using each metal
raw material was measured as the following sequence.
That is, the hydrogen generating system comprised of each metal raw
material 500 mg and malic acid 500 mg (or aluminum potassium
sulfate if the metal raw material is aluminum) was stored in a
polypropylene tubular hydrogen bubble forming implement (e-3)
without being covered by a cover material. The selective hydrogen
adding equipment for living organism applicable fluid according to
the present invention was obtained by dropping 500 mg of Fujisawa
city tap water (generating-purpose water) into the hydrogen bubble
forming implement, and closing the opening of the hydrogen bubble
forming implement with a gas-permeable film (Monotoran Film, Type
No.: FP10-01105-100, Nac Corporation) as the gas/liquid separating
section (e-4).
Subsequently, a PET bottle for carbonated drink (about 530 cc
volume when filled with full water to the mouth) was substantially
filled with about 515 cc of clarified water (charcoal-treated water
obtained by treating Fujisawa city tap water to pass through a
charcoal column), and the selective hydrogen adding equipment for
living organism applicable fluid was then disposed into the
clarified water in the PET bottle.
The bottle was closed with its cap and left during 5 minutes.
Thereafter, one of the present inventors (Japanese man of 30's
having an average physical size) held the middle portion of the PET
bottle by his dominant hand and moved only the wrist to shake it
such that the cap was forming into an arch above the wrist with a
pace of 2 strokes per second, total 120 strokes (total 60
seconds).
Then, DH concentration was measured.
As shown in Tables 4 and 5, Examples 11 to 17 and Comparative
Examples 2 and 3 are satisfactory as for DH concentration. However,
when measuring the temperature of metal raw materials by the "metal
raw material heat generation temperature measurement method",
Examples 11 to 17 use metal raw materials of which the exothermic
reaction is moderate or less, i.e. the temperature thereof is below
50 degrees (Examples 14 to 17) or the metal raw materials require 5
seconds or more before reaching 50 degrees C. if exceeding 50
degrees C. (Examples 11 to 13), whereas Comparative Examples 2 and
3 use metal raw materials of which the exothermic reaction is
severe such that 50 degrees C. are reached within 5 seconds.
Therefore, it can be said that a configuration suitable for the
selective hydrogen adding equipment for living organism applicable
fluid according to the present invention is of Embodiments 11 to 17
rather than Comparative Example 2 and 3.
